Optical fiber is short for optical fiber. It consists of a fine glass wire with a diameter of about 1mm. Because of its high transmission bandwidth and communication capacity, especially not subject to electromagnetic interference, it is favored by the enterprise LAN Integrated Wiring. Based on the comprehensive wiring specifications and the characteristics of Enterprise LAN construction, the selection of o

When you need to connect a newly purchased Soundbar or AV receiver to a device in your home, you are bound to have two main audio lines connected: HDMI and fiber. Perhaps for most users, HDMI is actually the simplest choice, but if you understand the characteristics of the fiber audio cable, it might not be easy to choose the HDMI way to connect. In general, both HDMI and

1 Overview At present, after completing the network transmission infrastructure construction, China's major communication operators have made full use of the bandwidth of the existing transmission link and sought new value-added communication services to increase business profits. The implementation of e-commerce and e-government, as well as the development of telephone bars, Internet cafes, and other small-and medium-sized Telecom customers have seen the recent boom in Man and the increase in

Optical fiber category (1) There are many types of optical fibers and various classification methods. From the material point of view According to the materials used for optical fiber manufacturing, there are Z optical fiber, multi-component glass optical fiber, plastic package layer Z core optical

At present, fiber-optic access networks are still one of the most common access networks. their special features include large communication capacity, high quality, and high flexibility. We believe that with the rapid development of the communication industry, the optical fiber access network technology will be more powerful. From the perspective of the entire telecommunication network, the whole network ca

"Netizen asks a question": have been not clear exactly what difference does photoelectric converter, fiber transceiver, light cat, light module have? "Answer": Optical module is inserted in the router or switch, can not be used independently, belong to other devices part. and netizens mentioned (photoelectric converter, optical transceiver, light cat, optical module) A few things are basically one thing, and the name is not standardized, more ambigu

As one of the most important devices in the storage system, fiber channel switches are widely used. I believe many consumers do not know how to buy them, the following is a detailed analysis of the selection of fiber channel switches. The fiber channel network built through the fiber channel (FC) switch is called Fabri

I. Overview As information technology is increasingly developed, data transmission is extremely important, in order to meet the needs of high-speed local computer networks, conference television, video-on-demand applications, and other applications, it is becoming an important topic of material science to seek information transmission media with a higher speed and Information Transmission volume. At present, in the process of information transmission, we can use copper cables with metal as media

Optical fiber In the erection, after the completion of the weld test work, the use of the instrument is mainly OTDR tester, with the Canadian EXFO ftb-100b portable Chinese color touch screen OTDR tester (Dynamic range of 32/31, 37.5/35, 40/38, 45/43db), you can test, The position of optical fiber breakpoint, the whole loss of optical fiber link, the loss distrib

After reviewing the network development process, we will all feel that the network is evolving with each passing day, and network applications have been updated and upgraded almost every several years, the continuous development of network applications puts forward higher bandwidth and other related performance requirements to people. With the popularization and application of gigabit and 10-Gigabit networks, in our traditional cabling system, currently, copper cable systems can only be used for

sun and rain, the water is split from the thin area of the outer skin, make the external conductor metal layer or metal mesh) corrosion. When the fault is checked with A multimeter, If the measured loop resistance is much higher than the original cable loop value, it proves that the outer conductor is seriously corroded. If the measured loop value is infinite, it indicates that the outer conductor is broken after corrosion. In short, there are many methods for detecting coaxial cables. As long

Network cabling and optical fiber technology is one of the most popular cabling technologies. to master this technology, you must fully understand its characteristics, performance, and precautions. Today, I will introduce you to this topic and hope to help you. After reviewing the network development process, we will all feel that the network is evolving with each passing day, and network applications have been updated and upgraded almost every severa
